From Wikipedia:
"Project Natal (pronounced "na-tall"(IPA: [naˈtal])) is the code name for a "controller-free gaming and entertainment experience" by Microsoft for the Xbox 360 video game platform. Based on an add-on peripheral for the Xbox 360 console, Project Natal enables users to control and interact with the Xbox 360 without the need to touch a game controller, through gestures, spoken commands,or presented objects and images. The project is aimed at broadening the Xbox 360's audience beyond the hardcore base. Project Natal was first announced June 1 at the 2009 Electronic Entertainment Expo. Microsoft said that over 1000 development kits began shipping to game developers that same day. Microsoft has not revealed any price or release date information for Project Natal.
Sensor device
An approximately nine-inch (23 cm) wide horizontal bar connected to a small circular base with a ball joint pivot, the Project Natal sensor is designed to be positioned lengthwise above or below the video display. The device features an "RGB camera, depth sensor, multi-array microphone, and custom processor running proprietary software", which provides full-body 3D motion capture, facial recognition, and voice recognition capabilities. The Project Natal sensor's microphone array enables the Xbox 360 to conduct acoustic source localization and ambient noise suppression, allowing for things such as headset-free party chat over Xbox Live.
The depth sensor consists of an infrared projector combined with a monochrome CMOS sensor, and allows the Project Natal sensor to see in 3D under any lighting conditions. Project Natal is reportedly based on software technology developed internally by Microsoft (gesture recognition, skeletal mapping, facial recognition, voice recognition) and hardware technology acquired by time-of-flight camera developer 3DV Systems. Before agreeing to sell all its assets in March 2009, 3DV had been preparing a similar device, known as the ZCam."
Interesting stuff.
This means that there is a custom processor doing all the hard work which leaves the core to get on with the games based stuff. With this in mind it may actually work as well as Microsoft and Lionhead say.
However, bearing in mind that these videos are pretty much tech demos and that the first reports from people who've tried this (such as Eurogamer have shown that Milo, the interactive boy , isn't quite as interactive as the team made out, I still think this could have a lot of potential for bringing more 360 units into the living room.
All that remains to be seen is the cost, availability and the software available. But with Microsoft's clout and contacts there should be a fair few interested third parties already starting to get their hands on the tech.
